1.2 Basic Configuration
1.2.1 Basic configuration
The following devices are required to operate the inverter. Proper peripheral devices must be selected and
correct connections made to ensure proper operation. Incorrect system configuration and connections can
cause the inverter to operate improperly, its life to be reduced considerably, and in the worst case, the
inverter to be damaged.
Please handle the inverter properly in accordance with the information in each section as well as the
precautions and instructions of this manual. (For connections of the peripheral devices, refer to the
corresponding manuals.)
Name Description
Power supply
Use the power supply within the permissible
power supply specifications of the inverter.
(Refer to page 193.)
Earth leakage
circuit breaker
(ELB) or no-fuse
breaker (NFB)
The breaker should be selected with care
since a large inrush current flows in the
inverter at power on. (Refer to page 32.)
Magnetic
contactor
The magnetic contactor need not be
provided. When installed, do not use it to
start or stop the inverter. It might reduce the
inverter life.
(Refer to page 32.)
Reactors
The reactors must be used when the power
factor is to be improved or the inverter is
installed near a large power supply system
(1000KVA or more and wiring distance
within 10m (32.81 feet)). Make selection
carefully.
Inverter
z
The inverter life is influenced by ambient
temperature. The ambient temperature
should be as low as possible within the
permissible range.
This must be noted especially when the
inverter is installed in an enclosure.
(Refer to page 7.)
z
Incorrect wiring might lead to inverter
damage. The control signal lines should
be kept away from the main circuit to
protect them from noise. (Refer to page
10.)
Devices
connected to the
output
Do not connect a power capacitor, surge
suppressor or radio noise filter to the output
side.
The AC reactor is recommended when the
long distance motor cable is used.

To prevent an electric shock, always ground
the motor and inverter.
